Hi .In this video I'd like to show various samples of installing 13 amp FCU / Fused connection unit often used as a fused spur in a ring final circuits. Please subscribe to my channel.
I've been googling and googling how to wire in an FCU for washing machine but I specifically want to see the actual physical wiring. This is the best video i have seen on this that both explains the theory/logic and shows a practical wired example. Very good!
His calculation has slight problems on the elctronic side. He did basic calculation but that is not how it works in the real world. In the heater there will be some form of small electronic board which convert the voltage to a very high voltage and will only need may be one or two amps [some time only milli amps], thus one has to be very carful what you put in the FCU because it can damage either the heater or other equipment connected to it. Ideally it should not be more than 3 amps but if one put 13 amps and there was a fault inside the electronic board the heater is good by....
I’m currently studying being an electrician. My training says to switch 13A fuse for a 3A fuse in the FCU, and also new practice is now to use 1.5mm cable
An electrician quoted me £200 to fix a FCU and single plug socket for my projector. ....Just went to B&Q and bought the bits and will follow this. Thanks mate.
I'm currently dealing with a fault on a spur line and this is an excellent explanation! You have enabled me to isolate the fault to the switched live out! Good work! ****
Thank you so much. You helped me out big time. Now I know where to add a fused spur. I love the way you draw it all out and explain everything so patiently. Thank you once again. 🙏
I was thinking of doing exactly as illustrated for a range hood, was unsure to meet BS regs. Your video has given me that surety. Thank you very much. I have subscribed to your channel. Cheers.
Thanks. Helped me with telling my kitchen fitters that one 13amp FCU isn't the correct connection for washing machine, dishwasher and tumble dryer and telling me to only have one on at once isn't very professional or acceptable. Apart from it being dangerous as the fuse melted into the fuse holder when too much power was asked for.
Very clearly explained, made it easy to understand. I have fault on my Under Floor heating and I think it is blown due to builders using 45A DP switch.
Hi, thank you for the video! Again another great explaination for us DIY'ers! Just want to clarify, have you used a 2 pole FCU? If so, is it safer to go for a 2 pole as it cuts off the Live as well the Neutral.
Good video and I agree that there can only be one unfused spur per socket on the ring. Having said that, surely, though maybe not the best idea, two 2.5kw heaters plugged into a double socket should be fine. (2 x 2500watts) / 240volts = 20.83amps, with both sockets rated 13amps and the wire is rated 26amps. If any of those went on fire then surely they weren't up to standard. The rating should be the safe limit with a safety margin calculated in.
Very informative videos. Thanks for making them. I have a question. I live in an old house, there's sockets only on one wall. There's 2 outlets 2 light switches and an fcu that is connected to the water heater for the bathroom. I want to have a socket on the opposite wall. The closets connection is the fcu. Is there a way to run a cable or buy a different fcu so I can add an outlet from there without having to switch it on, as that will switch on the water heater.
Hi, great video, just had a question would appreciate answer, What tests would you run before installing any additional sockets/spur onto an existing ring? What tests would you run if there isn't RCD protection at the fuse box and had the old style rewirable fuses? Many thanks
Hi, that's exactly what I needed. But some said you can have the FCU from the ring, not from socket. which is correct? here is what I found: " Can I run a fused spur off a spur? So basically a spur of a spur is never permitted, even if its fused. I'll have to just stick in a juntion box in the ring cables under floorboard and get a fused spur off that. Put a 13amp unswitched spur adjacent to the socket, then you can run whatever you like within reason from the outgoing or load side of that."
Hi, thanks for your really helpful videos. I wonder if you can help me. I am replacing a spurred socket with 2 FCU's. One FCU to connect to 3 new double sockets, and the second FCU to connect to a new LED batten and one-way switch. When I remove the original socket, there's just the one 2.5mm Twin & Earth cable. How can I connect that to 2 FCU's which will be situated next to each other? Do I need to go back further down the original spurred socket cable to the socket on the ring, and feed two 2.5mm Twin & Earth cables to the 2 FCU's?
I have an fcu (5amp ) serving a light switch for spotlights. I want to add a double socket off the fcu. I assume I replace fcu with 13 amp fuse and wire the connection for the double socket to the fcu using the supply terminals ?
If using a fcu 13amp connected to 3 switches can you connect a separate cable into the same fcu and power 3 sockets? If so then can you put in an additional fcu 5amp to power lighting straight off the 13 amp fused sockets?
Great presentation.answered a question that's been nagging me about a little job I have to do. However... yoirvideo f***ed with my head ,I thought I was having a migraine as there is a yellow bar running vertical across the screen, thought I was seeing things. Anyway,great video.
Hi, can another feed be taken from the FCU for a separate socket please? The FCU is already supplying 2 spur but would make my work easier if I can take the feed from the FCU. Thanks
Hi, i have a question! Probably silly but what if i dont want to take the cable out from the socket but instead want to use a 3 pin plug, can i still follow the same example for fcu? Im trying to add a cooker hood and washing machine but the plug is far! I dont want to take it of a socket so instead i wanted to create a extended socket with a 3 pin plug but add a fcu in between. Is that ok to do?
I'm still learning about domestic electrical mains, and I came across a problem I need help with: In my store room, I have an unused FCU switch connected to the mains, which used to be connected to the boiler. The boiler has since moved, hence the FCU now being unused. From that FCU there is a spur to another FCU for the jets in my bath How many sockets can I connect off of that mains FCU for things like 2 servers, routers, low powered PCs etc? I doubt they will use 13A in total. Someone has told me to simply replace the FCU with a double socket, but I need multiple sockets. So, my question is how many sockets can I spur from that mains-connected FCU? Please help.
i have taken a double spur from ring circuit and fixed a 13amp geyzer switch to it and used it to add 6 extra double spurs for my items of aquarium tank including heaters filters etc..and wired them with 2.5 wires..i did ok or not??
Question. I'm adding a dishwasher to my kitchen. I was just going to add a socket under the counter. Is it an absolute requirement that I install an FCU above the counter as well, or just a nice-to-have?
Hello, What are the regulations/correct way of wiring a Beko built in oven rated at 2.3 KW and the cooker hood? Can I used 2 FUSED spurs each wired back separately 2 a dual 13 amp socket? Can I feed them both directly from the back of the 13 amp socket? Will there be enough room in the socket to terminate the hood and the oven? Do I have to wire them both separately?
